Just looked at the most recently sold PSA graded cards on Ebay out of curiosity from the graded perspective:
VG-EX 4 Vance #2 $480
VG 3 Foxx #29 $625
VG-EX 4 Frisch #49 $252
VG 3 Ruth #53 $9,000
VG-EX 4 Cochrane #76 $308
VG-EX 4 Speaker #89 $425
VG-EX 4 Gehrig #92 $4,755
VG-EX 4 Ruth #93 $11,500
VG-EX 4 Hornsby #119 $675
G 2 Ott #127 $240
VG-EX 4 Ruth #144 $13,499
VG-EX 4 Foxx #154 $855
VG-EX 4 Berg #158 $525
VG-EX 4 Gehrig #160 $4,950
VG-EX 4 Ruth #181 $13,311
VG-EX 4 Hornsby #188 $441
VG 3 Ott #207 $335
VG-EX 4 Wilson #211 $475
VG-EX 4 Gehringer #222 $468
VG-EX 4 Dean #223 $625
Add that snapshot of 20 of the better cards and you get $63,744 (sure I missed some and hopefully I typed them right) Of course the Ruth cards will whammy you the most totaling up to over $40,000
Figure $150 for the rest of your HOFers (don't want to check the whole set
) so let's just say the remainder after the above list leaves you around $2,000(probably more)
Call your commons about $60 so let's say $12,000 or so
So my guess would be around 65k in the graded VG-EX range give or take(plus any tax/shipping/fees) and trending up
Just for fun, a VG 3 Lajoie sold this summer for $43,200, so roughly 110k for a truly complete set. 125k+ if the Lajoie was a 4?
